Twenty varieties of grapes are grown yielding an average annual crush of 450 tonnes. The wine is completely processed on the property including the bottling of the finished wine (35,000 cases per year). This is a far cry from the pioneering days of the first Jesuit winemaker Br Schreiner. He and Br Schneider built a wine press in 1863 capable of pressing a formidable load of 4 buckets of grapes at a time!
The production of altar wine today accounts for 30% of the winery's production. Made in the style of a sherry and in conformity with the requirements of Canon Law is sold to all Christian denominations in Australia for use in religious services. It is exported to India, Indonesia, Papua New Guinea, Singapore, Guam, Borneo and Pacific Isles.
In the history of Sevenhill Cellars, there have been 7 Jesuit Brother Winemakers. In September 1851 Br Schreiner bought some vine cuttings from Bungaree Station and planted them on the left hand side of the present road to the winery. This planting marks the beginning of Sevenhill Cellars and makes it the oldest winery in the Clare Valley. These vines were planted initially to meet the need for altar wine.
